Letters Patent No. 111,062, dated January 17, 1871.

IMPROVEMENT IN COMBINED SEED-DRILLS, MANURERS, AND, POTATO-DIGGERS.

The Schedule referred to in these Letters Patent and making parl: of the same.

which will enable others skilled in thc art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a new and useful improvement in seed-drills and potato-diggers, and to a combination of the two machines, and consists in the feedcylinder for-distributing tleseed and fertilizer, and in a partition iu the hopper, by which the seed and the fertilizer are separated, and in the employment of a rerevolving chain-apron with revolving wingsfor carrying and properly sifting the potatoes after they have been raised from lthe ground, and in the combination of the seed and manure-drill and potatoedigger, the two being arranged to operate separately on the same pair of traction-wheels, as will be hereinafter more fully described. d

In the accompanying drawing-1 y Figure 1` represents a vertical section of the machine taken on theline z x'of lig. 2.

Figure 2 is a vertical'sectio'u taken on the line y y of iig.1v. i p

Figure 3, Sheet vII, isa view ot' the yunder side', the

machine being reversed to show the endless chain and revolving wings.

Similar letters of reference indicate corresponding parts. TheV operating parts of this combined machine are' actuated by means of two traction-wheels A and B. f C is a frame with double longitudinal rails', which supports a short axle for each of the wheels.

Upon each aile there is a spur-wheel, D, from one of which motion is imparted, to drive the distributingcylinder E, beneath the hopper.

F is the'spnr-whecl, on the endof the shaft of the distributing-cylinder.

Each ofthe spur-wheels'has bevel-cogs on their inner sides, from which 'motion is conveyed to the shaft G of the potato-digger endless chain. This arrangement is plainly seen in fig. 2. v

The bevel-wheels H HP are supported by brackets I I, which are attached to the leversJ J.

By removing the small pins K'K which pass through holes in the levers, the operator is enabled'to throw the bevel-wheels out of gear, so as to stop or prevent the rotation of the endless chain.

L L are the shafts of the bevel-'wheels H H.

0n thc ends of these'shafts are'ratc-het-wheels, with spring-pawls on the backs of the bevel-wheels, the ratchets and'pawls being so arranged that the bevelwheels willbe revolved only when the machine is moving forward.

Aj back movement causes the pawls to slip over theteeth of the ratchet. This arrangement 'is plainly seen in the reverse view, 3.

M is a potato-digger share and inclined plane, the forward end of :which is designed to run beneath the rowsor hills of potatoes.

As the ,machine moves forward the potatoes and earth are shoved up theinclined plane together and delivered onto the loose wire grate-rods Ns These rods N are attached to the top of the inclined plane,

and extend back and bend down over the backend of the chain, as seen in lig. 1.

O represents the' endless chain, which, as before stated, is revolved by means of the shaft Gr.

P represents the wings of the chain O, which cxtend across from one chain to the other, with small cog-wheels q upon, the ends of their shafts. These wheels engage with the stationary cogged racks It R.

It will be seen that-as the chains which carry the wings are revolved the wings will receive an independent rotary motion, and that as they revolve they will agitate the rods'N and effe'etnally clear the p'tatoes ii'om earth. The earth will drop betweenlthe wings as the potatoes are moved back, while the potatoes are delivered upon the surface of the ground clean and ready for market.

vS is the shaft of the seed-drill and mannring-cylinder E.

T is the hopper.

U is a partition which dividesl the hopper into two parts, one Vfor the seed, and the other for the fertilizer.

The distributing-cylinder .E has two sets of cups `or cavities, which receive the seed and fertilizer as the cylinder revolves under the compartments of the hopper', from whichY cups orcavities they drop at uniform intervals.

The quantity of the seed, as well as of the fertilizer,

is regulated by theslides U', which are dovetailedinto the cylinder, and are adjustable, as may be desired.

The cups or cavities are constructed so as to receive and deliver the seed and' fertilizer to the best advantage.

By forming separate compartments in the hopper and separate cups orcavitieslin the distributing-cylinder, veither compartment can be used Awithnnt the other, as may Abe desired.

W is an'agitating-rod,which passes horizontally through the hopper, with wire teeth therein', as seen in figs. l and 2. y

This rod-is revolved by means of the pinion-wheel X on its end, which engages with the spur-wheel Y on the end ot the distributing-cylinder shaft, seen in.

. moved i-om the frame G when the potato-digger is in use; andthe potato-digger is so constructed and supported that it may be removed when it is desired to use the d1-ill; but the same wheels and general supporting-haine C, which embrace a large portion of the expense of a seed-drill, as well as a potato-digger, are used for both objects.

By combining,r the two machines, as shown and described, thev expense is greatly reduced, while all the advantages'of two machines of t construction are secured.

, Having thus described our invention, We claim as new and desire to secu Patento y 1. In.combination with a. potato-digger, the chain O, with Athe rotating-wings l and wires N, arranged he most approved re by Letters shown and described.

2. The stationary racks R R, for rotating the wings ofthe endless chain, lsubstantially as described.
